Track the changes you'd otherwise miss, stay on top of care, and get answers grounded in your own cat's profile and history between vet visits.

The useful answers scrolled away, and the subtle changes that matter with cats — appetite, energy, habits — had nowhere to live. ## The app we built NineLives takes the questions her community kept asking and gives them a permanent home: a health record for each cat, reminders that keep care on schedule, and guidance that knows the cat it's about. Everything in one place instead of scattered across a feed. ### What the app does - Health and behavior tracking, whether you have one cat or a houseful - Answers personalized to each cat's profile and history, not generic pet advice - Reminders for care routines, medications, and checkups - A running record that catches the subtle changes owners tend to miss ## What BUILT BY FOUNDRY handled - Took a broad pet-loving audience and shaped it into a focused product: cat health, tracked properly - Designed the whole experience — cat profiles, tracking, reminders, and personalized guidance, including multi-cat homes - Wrote the code, built the iOS app, and carried it through App Store review to launch - Handle everything after launch too: maintenance, fixes, and ongoing product improvements ## Public evidence Everything below is a fact you can check without taking our word for it. We deliberately leave out private revenue claims and projections — the links go to public pages that show the app is real, live, and genuinely this creator’s. - Open the App Store listing and the byline reads 'By Samantha Mae, Cat Mom.' — Apple's page, not ours. - That same listing names BUILT BY FOUNDRY, INC. as the current developer, so the partnership is on the public record. - Our NineLives product page links out to Phoebe the Scottish Fold's public creator profiles — anyone can trace the connection themselves. ## Sources and verification [**NineLives - Cat Health Tracker**Apple App StoreApple's public listing · accessed 2026-07-14](https://apps.apple.com/us/app/ninelives-cat-health-tracker/id6753718987)[**Phoebe the Scottish Fold**TikTokThe creator's public profile · accessed 2026-07-14](https://www.tiktok.com/@phoebe.thescottishfold)[**NineLives product page**BUILT BY FOUNDRYOur own product page · accessed 2026-07-14](https://www.builtbyfoundry.io/ninelives.md) ## How we wrote this We wrote this case study from our own build records, then checked the creator’s public profile, the product page, and the independent App Store listing on 2026-07-14\.
